While infinity pools and garden pools are trending in India, thanks to the enviable villas in places such as Kerala, Rajasthan, Goa and as far as Kashmir (all of which you can rent as your holiday home), there is a new kind of swimming pool that is starting to gain popularity in the region. They are called natural pools or swimming ponds, this type of pond uses a natural filtration system with regeneration zones, which without the use of any chemicals or machines cleans and purifies the water to achieve a healthy level for swimming purposes. As a result, these pools are not only environment-friendly but are also a healthier alternative for the household.
Installed into your swimming pond will be the necessary organisms and plants that will (hopefully) keep your swimming pond water crystal clear. Algae numbers in the pond are constantly managed by zooplankton and a natural 'filter' that is installed at the time of construction. This is a huge contrast to the number of chemicals needed to keep a conventional pool clear.
The natural filter consists of layers of shingle and other mineral-type materials, which the water is pumped through, in order to remove any debris. The plants growing in and around the pond also suck up any extra nutrients (algae), to prevent blooms occurring (which turn the water murky).
What type of plants should I use in my natural swimming pool?
Hydrophobic or hydrophilic is a type of water plant that is ideal for those who want to make their swimming pond not just practical, but also beautiful. Some species are totally submerged but there are also other types that keep only roots and stems inside the water. Have in mind that there are some species that are only for decorating and landscaping purposes, you also need others that are ideal for keeping the balance of your pond ecosystem. Don't worry about those plants that live fully underneath the water, because they can get the nutrition that they need directly and solely from the water, no matter if they have shorter or longer roots. Some of these plants are floating and have very short roots that won't disturb other things. For your swimming pond, we recommend white lotus, Victoria-Regia, lotus, water reed, leather hat, water lettuce or Murray tick.
Where should I build my natural pool?
Ideally, the terrain should be flat and away from ripples, ravines, wetlands, and rocky areas. Aside from that, professionals also advise against placing them in old embankments, recessed locations, and under trees and roof gutters, which will make cleaning and maintenance much more complicated. Most structures of this type have a depth ranging from 0.4 to 0.8 m and a perimeter of approximately 1m or 1m20cm. This type of pool can also take on any form, although the rectangular shape is the most common.
How can I keep my swimming pond clean?
The pH of the water should always be measured with specific appliances and the carbonate level is the same. Nitrogen compounds are another important point to watch out for, which is released with fish feces (if you decide to put fishes as well). This can be controlled with efficient filtration, which avoids the need for partial or total exchange of lake water. Placement of a bio-filter and installation of pumps are also a good idea, the same goes for filters and water pH meters of your water system. If you are unsure, our advice is to consult with a pool and spa professional. They will be able to guide you about what should be the ideal size of each equipment and other details to have the beautiful detail in the garden without major concerns. Another very important detail is that the filter cleaning box should be installed in an easily accessible location, and can be hidden with some plants.
What are the pros and cons of owning a natural pool?
Organic or natural pools require much less maintenance than a conventional pool, and their year-to-year costs are lower after construction is finished. They don’t require chlorine, chemical filtration, pH balancing, or any of the other side costs that go with keeping a normal pool clean. They should still be kept well-skimmed and free from debris, but that’s really the extent of the maintenance you’ll need to do with your pool. Because the pond is naturally filtered, there is no need for chlorine-based chemicals. This is brilliant for those who might be allergic to chlorine, plus you eliminate the extra hassles of having to balance chemicals.
In the summer there is a possibility that a lot of algae will grow in the pond covering the surface of the water, hindering photosynthesis of other plants and killing them all. It is also conceivable that other living things of the pond dies due to oxygen shortage. That’s why it is necessary to remove these algae and filter the water.
The swimming pond is also very attractive to children, so make sure you are prepared enough with security measures to prevent them from drowning.
